x = 3

#### Explanation:

**1. Subtract 2 from both sides** to isolate the square root.

**2. To get rid of the square root**, square both sides.

**3. Subtract 1 from both sides** to find x.

Now that we know that x = 3, check the solution by plugging its value back into the original equation.

The solution, x = 3, works!
